Shock Dyno Testing: What Your Damper Curves Are Hiding | LABA7

What can shock absorber testing reveal about cavitation, seal friction and damper performance? LABA7 explores how crank dynos and electromagnetic testing technology help race teams, suspension tuners and engineers understand what happens inside a damper.

In Race Industry Now Episode 639, discover how programmable test inputs, track-data replay and high-resolution measurements can reveal behavior that conventional sinusoidal tests may miss—and how excessive filtering can hide valuable diagnostic information.

Featuring:
• Andrius Liškus, CEO & Head of R&D, LABA7
• Andrius Petkauskas, Co-Founder & Head of Software, LABA7

Hosted by Brad Gillie from SiriusXM, Ch. 90, Late Shift.

Topics covered:
• Crank / Scotch yoke dynos vs. servo-hydraulic and electromagnetic testing machines
• Force vs. velocity and force vs. displacement analysis
• Constant-velocity testing for friction and stiction investigation
• Frequency sweeps, pink noise and recorded racetrack inputs
• Identifying signatures associated with cavitation and aeration
• 20 kHz EMA sampling and how filtering affects damper analysis
• Temperature-controlled testing and automated pass/fail checks
• External sensors, side-load testing and simulation validation
• Upcoming high-velocity and fatigue-testing equipment

Whether you’re matching racing shocks, developing damper valving or troubleshooting suspension performance, this discussion offers practical insight into choosing test methods and interpreting the results.
